Hi I have created two GtkWidget like this
GtkWidget* set_coverlcd_contrast_vbox = NULL;
GtkWidget* set_coverlcd_contrast_image = NULL;
now my create function is like this ,, In this i have given key press event "contrast_keypressed" to the set_coverlcd_contrast_vbox
create( state_t* pState, gint winAct )
{
state_t* this = (state_t*)pState;
set_coverlcd_contrast_vbox = gtk_fixed_new();gtk_event_box_new ();
gtk_widget_set_size_request (set_coverlcd_contrast_vbox, 240, 216);
gtk_widget_set_events (set_coverlcd_contrast_vbox, GDK_KEY_PRESS_MASK);
gtk_signal_connect(GTK_OBJECT(set_coverlcd_contrast_vbox), "key_press_event",GTK_SIGNAL_FUNC(contrast_keypressed), this);
gtk_fixed_put(GTK_FIXED(WsGetMainArea(this->set_main_window)),set_coverlcd_contrast_vbox, 0,0);
set_coverlcd_contrast_image = gtk_image_new();
gtk_widget_set_size_request (set_coverlcd_contrast_image, 240, 216);
gtk_misc_set_alignment (GTK_MISC (set_coverlcd_contrast_image), 0, 0);
gtk_fixed_put(GTK_FIXED(set_coverlcd_contrast_vbox),set_coverlcd_contrast_image, 0,0);
gtk_widget_show(set_coverlcd_contrast_image);
__psh_set_coverlcd_contrast_loadbmp( this, gpsh_set_coverlcd_contrast_level );
gtk_widget_grab_focus(set_coverlcd_contrast_vbox);
gtk_widget_show(set_coverlcd_contrast_vbox);
}
gboolean
contrast_keypressed( GtkWidget *widget, GdkEventKey *event ,gpointer data )
{
switch( event->keyval)
{
case 65361:
fprintf(stderr, "left keypressed ..\n");
case 65362:
fprintf(stderr, "up keypressed ..\n");
case 65363:
fprintf(stderr, "right keypressed ..\n");
case 65364:
fprintf(stderr, "down keypressed ..\n");
return FALSE;
}
my problem is the event handler is not getting called when i press left,up, right, down keys
what could be the problem?? |
